Indicator Report - Obesity Among Adults
Why Is This Important?Adults who are obese are at increased risk of morbidity from hypertension, high LDL cholesterol, type 2 diabetes, coronary heart disease, stroke, and osteoarthritis. Obesity is the second leading cause of preventable death in the United States. Only smoking may exceed obesity in contributing to total U.S. mortality rates.
Data NotesObesity is defined as a BMI of 30 or more. BMI is calculated by dividing weight in kilograms by the square of height in meters. Age-adjusted to U.S. 2000 standard population using three age groups.
Beginning in 2011, BRFSS data include both landline and cell phone respondent data along with a new weighting methodology called iterative proportional fitting, or raking. This methodology utilizes additional demographic information (such as education, race, and marital status) in the weighting procedure. Both of these methodology changes were implemented to account for an increased number of U.S. households without landline phones and an under-representation of certain demographic groups that were not well-represented in the sample. This graph is based on the new methodology. More details about these changes can be found at: http://health.utah.gov/opha/publications/brfss/Raking/Raking%20impact%202011.pdf.
